Events in Los Angeles This Weekend: SIP Workshop and Maria’s Garden

Saturday (i.e. TODAY!)

On Saturday November 14th Kelly and I will be doing a Self Irrigating Pot (SIP) workshop in Westchester at 3 p.m. SIPs are a great way for folks in apartments to get into small scale vegetable gardening. Best of all the workshop is FREE FREE FREE! Here’s the location:

Playa Del Oro at 8601 Lincoln Blvd, Los Angeles, CA 90045

Sunday

Anne Hars, who lives a few blocks from us, helped save another neighbor’s garden from a management company that wanted to remove it. Tomorrow, Sunday the 15th, Anne has organized a work party to tidy up the garden and she’s looking for volunteers and a few donations of pots, mulch and soil. The fun begins at 9 am at 421 North Coronado Street.

“This is a great opportunity to help a Senior Citizen in need and spend the day puttering around in the garden! We need people of all skill levels from beginners to experts. Landscape Designer Maggie Lobl has kindly worked out a design approach and will help co-ordinate activities.”

Humanure Happens

Simparch’s dry toilet located in Wendover Utah

From the 1806 edition of the Old Farmer’s Almanac,

“Four loads of earth mixed with one load of privy soil, will be equal to five loads of barnyard dung. Let it lie for several months and occasionally turn it over with a shovel, and it will be of use as manure.”

The editors of the Old Farmer’s Almanac 2010,where I found that quote, deemed it necessary to tack on a disclaimer, “Human waste, as well as that of dogs and cats, is not recommended as manure for fertilizer today.” But after fielding a couple of calls from journalists interested in the subject of composting human waste, I’m thinking that humanure is about to get serious consideration again. After all, why waste a good source of nitrogen in the middle of a recession?

Simparch’s striking Clean Livin’ compound

All this is a long winded intro to get you all to check out two fine examples of dry sawdust-based toilets. First is the one at the top of this post, designed by a collective known as Simparch, and located on the historic Wendover Air Force Base on the Nevada-Utah border. The facilities are simple: a toilet seat sits atop a 55 gallon drum. Each time you use it you add some sawdust. After composting, you’ve got rich soil. But what makes the Simparch crapper so amazing is the view. From the throne you look out on a landscape so flat you can see the curvature of the earth, punctuated by munitions bunkers dating back to World War II. The toilet facilities are part of a self-sufficient living project they call “Clean Livin‘”.

It ain’t the moon but close: the view from the Simparch Clean Livin’ crapper

The second example, nicknamed the “crap-cedral”, is featured on Lloyd Kahn’s amazing blog. Built by someone with the improbable name of Birchbarkbobananda, the crap-cedral features intricate woodwork and an equally stunning location. What both of these dry toilet facilities prove is the siting possibilities that can happen when you can put your crapper wherever you damn well please. No sewer line means you can have a nice view!

Rubber Sidewalks Rescue Trees

Homegrown Neighbor here:

I love trees and all of the things they do for us. They shade us, feed us, house us. Trees are something we just need more of here in Southern California.
I used to work at an urban forestry non-profit, TreePeople. So I am familiar with the challenges of the tree/sidewalk interface. I have fielded calls from people frantically trying to save trees that are being ripped out because they are lifting the sidewalk. I have also received calls from people eager to remove trees for the same reason. Sadly, I have also heard from people that would call just to complain about a tree being messy and littering their sidewalk or driveway. My personal take on that is it isn’t the tree that should be removed- it is the concrete. Leaves falling off of trees is a good thing. Leaves make glorious mulch or compost and that hardscape is just in the way of some healthy soil.
Nonetheless, in a city there are sidewalks. There are also commonly trees near sidewalks. The wrong species of tree or a tree that is too large for the available space, can lead to problems. Cracked or raised sidewalks can be hazardous or inaccessible for the disabled, people with strollers, cyclists, skate boarders and those of us who are just generally clumsy. Rubber tiles in place of concrete can be a solution. They allow the tree roots to grow yet they are flexible. They conform to the contours of the roots. This eliminates gaps and provides an even surface. They are safer than ordinary concrete and allow the tree to thrive as well. I have heard of these rubber tiles before but I had never seen them in person until just a few days ago. I came across this tree and the rubber sidewalk in a leafy, pretty suburb along a major boulevard with a lot of foot traffic. Viva el arbol!

More on this material via the Charlotte Observer,“When the rubber meets the sidewalk (at $80 a foot)”.

The company that makes them is called, not surprisingly, Rubber Sidewalks.

Apron Contest Winner

Homegrown Neighbor here:


We have a winner for our apron giveaway. I received a lot of great entries. It was fun to hear what each of you would do in an apron. I’m happy to say that we have a lot of interesting, witty and crafty readers. I even received some international entries. I wish we could give you all aprons.

But Katie Presley made me laugh, so I had to choose her as our winner. Lots of people cook and craft, but Katie cooks and crafts with an irreverent and sassy sense of humor. My kind of girl.

Her entry was rather long, so I’ll just give you the highlights. She said she would first roll around on the floor and wrap herself up in the apron like a “sexy burrito.”

She cooks, of course. She even makes her own recipe books of tasty treats. In addition to cooking she notes, I am also in printmaking, so this apron can come with me to my art classes to make the bindings for the recipe book for the recipes that Apron and I were JUST working on! It is an artistic, apron-centric circle of life.”

Congrats, Katie.

I’ve got a batch on jam on the stove, so I’d better finish this post and get to canning. I’m putting on my apron now….the jam is peaches with ginger, zero white sugar, a little maple syrup and unripe apples pieces for pectin. I’ll let you know how it turns out.

Another Panel Solar Cooker

Poyourow demoing her solar cooker design

There’s no one size fits all solution when it comes to the world of solar panel cookers. All have their advantages and disadvantages. I got an email from author Joanne Poyourow, leader of the amazing Los Angeles Environmental Change Makers, with a simple and effective design she came up with.

Pouyourow’s cooker comes together much faster than the CooKit design that I blogged about earlier this week. There’s hardly any cuts to make and no glue needed. Her design makes use of a car sunshade which can be picked up cheap at your local 99ยข store. The sunshade is more durable than aluminum foil glued to cardboard. While you can also fashion a sunshade alone into a solar panel cooker, I’ve found that they don’t stand up well in even a moderate wind.

Plans for Poyourow’s cooker can be found here (pdf).

She also has a list of solar cooking resources here.

And yes, for most North Americans this is the wrong time of year to be blogging on this topic since, as the sun gets lower in the horizon, solar panel cooking season is almost over. But I’ve got a backlog of summer R&D to share. Stay tuned for the ups and downs of our summer gardening, a bike accident story and a taste test of beer made with our homegrown hops . . .

CooKit Solar Panel Cooker


I’ve been experimenting with a nice panel solar cooker for the past week and, so far, the results are impressive. Called the CooKit, it was developed in 1994 by a group of engineers and solar cooking enthusiasts associated with Solar Cookers International and based on a design by Roger Bernard.

It has a couple of nice features:

  • It produces ample heat to cook rice and simple casseroles.
  • When you fold it up it takes up no more space than an album (do I have to explain what an album is for the youngsters out there?).
  • A flat area on the base of the CooKit makes weighting it down with rocks easy. This is really important in windy places.
  • All you need to build it is a knife, cardboard, aluminum foil and glue.

As with all panel solar cookers you need an black enamelware pot wrapped in a turkey roasting bag to hold in the heat. You ain’t gonna deep fry things with a panel cooker, but they are great for slow-cooked crock pot type dishes. The only disadvantage to this design is having to cut curves, but with a sharp knife it wasn’t difficult. The other improvement would be a stand to lift the pot off the aluminum foil for more efficiency and to keep the cooker un-scuffed. When panel cooker season returns to LA in the springtime, you can bet I’ll be making a lot of rice with this thing.

Detailed instructions for how to build a CooKit can be found here.

Also, Mrs. Homegrown and I are writing a new book and we’d like to include some plans for solar cookers (any kind). If you’ve got a favorite DIY model, leave a comment with a link.

Digital Farming- What’s The Deal?

Homegrown Neighbor here:

So here in the world of urban homesteading things can get pretty busy. We can become so preoccupied with work, chickens, vegetable gardening, cooking, cleaning, blogging duties and email that we can miss some of the things going on in the world. I do like to occasionally check in with the world at large by reading the newspaper. I just read an article that I have to comment on.

A recent New York Times article titled, ‘To Harvest Squash, Click Here,‘ introduced me to the world on online farming. Apparently people spend a lot of time “farming” on line. Twenty two million a day in fact, according to the article. There are several farming games on Facebook, Farmville being the most popular. You can get seeds to plant, watch your crops grow and then harvest them. Some people are so addicted that they are eschewing real life responsibilities and social obligations to harvest their virtual soybeans.
It is even suggested that the popularity of these farming games is indicative of a collective yearning for a more pastoral life. I’m not sure I get this. I spend all day outside in the dirt making things grow. At sundown, I lock up the chickens. Then I harvest something to make into dinner or on a special evening, I’ll make a big batch of jam or sauce and spend hours canning. I’d rather spend as little time online as possible.
I can’t wrap my head around how a video game can in any way replicate the experience of farming. I may be an urban dweller, but I get my satisfaction by getting real, not virtual, dirt under my fingernails. Can any one explain this trend to a clueless non-gamer like me?

Handmade, Homegrown Apron Contest

Homegrown Evolution reader Pam Neuendorf has offered fellow readers a chance to win one of her handmade aprons. She sells her wares through Etsy, a website where crafters and artisans can sell their goods. You can see more of her aprons here. She has an ordinary day job but is a maven of craft by night. Pam says, “I love making aprons. They make me happy.” I am a big fan of aprons. They are useful for cooking, gardening or just looking darn cute. I am also a big supporter of all things handmade. So I love this handcrafted apron.

I also hope our readers will appreciate this reminiscence of mine. -When I was in college I lived in a house with a lot of people. There were about 50 of us and we took turns cooking and cleaning. Every Friday we celebrated ‘Naked Pizza Fridays.’ Only the men would cook on Fridays. They would wear aprons and nothing else. Just the apron. Oh, the good old college days. Perhaps this is why I see aprons as slightly subversive and rather sexy.

Dear readers, if you would like to have this apron, send me an email and tell me what activity you would use your apron for. I want to hear about your hobbies and how this apron would help your creative energies. I will pick a winner by Sunday night. Send your entries to [email protected].

Quince: the “Poster Child of Slowness”

Oops–I think they mean “quince

A year ago I planted a “Karp’s Sweet Quince” tree from Raintree Nursery and blogged about it, saying that I’d like to hear from fruit expert David Karp for whom the tree is named. Karp called me a few weeks ago to say that he was working on a quince article for the LA Times, “There’s a new taste for quince“. In the article Karp discusses varieties that can be eaten raw as well as how our Southern California climate is an ideal place to grow quince. Karp asked how my tree is doing and I had to say that it’s not doing all that well. In a fit of mad, rare fruit tree planting fever, I put it in a crappy location, in bad soil too close to a large prickly pear cactus that is probably competing with it. We’ll hope it does better in the next season.

Filling in for my lack of backyard quince, Homegrown Neighbor was nice enough to pop by with some she bought local Asian market. The label must have lost something in translation, but refers to a variety called “Pineapple quince”. Karp points out in his article that this is the most prevalent commercial variety. When picked fresh it could conceivably be eaten raw, though the commercial stuff ain’t fresh.

Quince is indeed, as one of Karp’s sources notes, “the poster child of slowness.” I tried to make some jelly with it and greatly underestimated how long it takes to cook. The jelly did not set, so I’ll have to try again. But the fruit did fill the entire house with a heavenly scent. Definitely a fruit worth slowing down for.

A Warning About Straw

Claude Monet used straw (or is that hay?) for art. We use straw to catch chicken droppings!

Straw is a very inexpensive and useful material for composting, mulching and animal bedding (we use it for all of these purposes). If you use it for mulch you’ll probably get some seeds that will germinate, but I’ve never found it to be a big problem in a small vegetable garden. I get my straw from the feed store, but you can often get it for free from yuppies on Craigslist who have bought it to give their parties the Hee Haw ambiance we enjoy 24/7 at the Homgrown Evolution compound. If you buy it from the feed store remember to ask for straw, not hay. Hay is green and a lot more expensive. You feed hay to your horses.

But one warning from my friend, permaculturalist David Kahn. It’s tempting to pick up bales that stores have used after Halloween, but make sure they weren’t treated with fire retardant. Fire retardant has some nasty chemicals in it you don’t want in your garden. When in doubt, just go to the feed store–straw it ain’t expensive!

Addendum 10/27/09: Reader Polyparadigm raised another potential issue with using straw in your garden or compost pile: halogenated pesticide/herbacide residues. Clopyralid is an example–while banned for use in lawns in many places it’s still allowed on hay and grain crops . All the more reason to grow your own mulch and carbon materials if you can–don’t throw out those fall leaves! Here’s what Polyparadigm says:

“I’m glad I read through to the end! I was thinking this would be a warning about clopyralid and its close cousins. Which bears some mention: Halogenated pesticides aren’t broken down by any but a few soil organisms.

Clopyralid and aminopyralid mimic the hormones in broad-leaf plants, causing them to grow un-evenly and die from wrong-facing, crinkled leaves and other symptoms. Grasses are un-affected, so fields of grain and lawns have been sprayed with this sort of chemical, as a cheap way of keeping broad-leaf competitors at bay for a few years.

These chemicals have a half-life of 11 months in hot compost, and are often applied at such high rates that certain plants won’t grow in garden soil dressed with finished compost from a mix of sources, if one of those sources is a treated lawn or field.

A quick bioassay will test for this in straw: peas sprouting from soil mixed with that straw will look deformed if the field that grew the straw was treated. Browns of a similar texture from a source you know to be clean should probably be used for a control group.”
